Section 10 Conclusion
2.1.1.
“Wan Chai Development phase II and Central-Wan Chai Bypass” and
“Central-Wan Chai Bypass and Island Eastern Corridor Link” (hereafter called
“the Project”) are Designed Project (DP) under the Environmental Impact
Assessment Ordinance (Cap. 499) (EIAO). The Environmental Impact Assessment
(EIA) Reports for Central-Wan Chai Bypass and Island Eastern Corridor Link
(Register No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan
Chai Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001
and 11 December 2008 respectively.
2.1.2.
The key purpose of Wan Chai Development Phase II (WDII) is to provide
land at Wan Chai North and North Point for construction of the Central-Wan Chai
Bypass and Island Eastern Corridor Link (CWB). Land formed under the project
will be developed as a world-class waterfront promenade joining that at the new
Central waterfront for public enjoyment.
2.1.3.
There is a compelling and present need for the CWB to provide relief to
the very congested east-west Connaught Road Central/Harcourt Road / Gloucester
Road Corridor (the Corridor) which is currently operating beyond its capacity.
The CWB will provide relief to the existing congestion along the Corridor and
cater for the anticipated growth of traffic on Hong Kong Island. Without the
CWB and its access roads, there will not be sufficient capacity to serve the
heavy traffic demands at both strategic and local levels.
2.2.1.
The Project is located mainly in Wan Chai North, Causeway Bay and North
Point, and is demarcated by Gloucester Road and Victoria Park Road to the
south, Fenwick Pier Street to the west and Tong Shui Road Interchange to the
east, as shown in Figure 2.1.
2.2.2.
The study area encompasses existing developments along the Wan Chai,
Causeway Bay and North Point shorelines. Major land uses include the Hong Kong
Convention & Exhibition Centre (HKCEC) Extension, the Wan Chai Ferry Pier,
the ex-Wan Chai Public Cargo Working Area (ex-PCWA), the Royal Hong Kong Yacht
Club (RHKYC), the Police Officers’ Club, the Causeway Bay Typhoon Shelter
(CBTS) and commercial and residential developments.
2.2.3.
The scope of the Project
comprises:
·
Land
formation for key transport infrastructure and facilities, including the Trunk
Road (i.e.
CWB) and the associated slip roads for connection to the Trunk Road and for through
traffic from Central to Wan Chai and Causeway Bay. The land formed for the above
transport infrastructure will provide opportunities for the development of an
attractive waterfront promenade for the enjoyment of the public
·
Reprovisioning
/ protection of the existing facilities and structures affected by the land
formation works mentioned above
·
Extension,
modification, reprovisioning or protection of existing storm water drainage
outfalls, sewerage outfalls and watermains affected by the revised land use and
land formation works mentioned above
·
Upgrading
of hinterland storm water drainage system and sewerage system, which would be
rendered insufficient by the land formation works mentioned above
·
Provision
of the ground level roads, flyovers, footbridges, necessary transport
facilities and the associated utility services
·
Construction
of the new waterfront promenade, landscape works and the associated utility
services
·
The
Trunk Road (i.e. CWB) within the study area and the associated slip roads for
connection to the Trunk Road.
2.2.4.
The project also contains various Schedule 2 DPs that, under the EIAO,
require Environmental Permits (Eps) to be granted by the DEP before they may be
either constructed or operated. Table 2.1 summarises the five
individual DPs under this Project. Figure 2.1 shows the locations of these Schedule 2 DPs.

Due to the multi-contract nature of the Project, there are a number of
contracts sub-dividing the whole works area into different work areas to be
commenced. Contractors of individual contracts will be required by the EP
holder to apply Further Environmental Permits (FEP) such that the impact
monitoring stations are sub-divided accordingly to facilitate the
implementation of EM&A programme and to streamline the EM&A reporting
for individual FEP holders correspondingly.

Noise Monitoring
Parameters, Frequency and Duration
4.1.2.
The construction noise level shall
be measured in terms of the A-weighted equivalent continuous sound pressure
level (Leq). Leq (30 minutes) shall be used as the monitoring
parameter for the time period between 0700 and 1900 hours on normal weekdays.
For all other time periods, Leq (5 minutes) shall be employed for
comparison with the Noise Control Ordinance (NCO) criteria. Supplementary information for
data auditing, statistical results such as L10 and L90 shall also be obtained
for reference.
4.1.3.
Noise monitoring shall be carried out at all the designated monitoring
stations. The monitoring frequency shall depend on the scale of the
construction activities. The following is an initial guide on the regular
monitoring frequency for each station on a weekly basis when noise generating
activities are underway:
·
One
set of measurements between 0700 and 1900 hours on normal weekdays.
4.1.4.
If construction works are extended to include works during the hours of
1900 – 0700 as well as public holidays and Sundays, additional weekly impact
monitoring shall be carried out during respective restricted hours periods.
Applicable permits under NCO shall be obtained by the Contractor.
Monitoring Equipment
4.1.5.
As referred to in the Technical Memorandum ™ issued under the NCO, sound
level meters in compliance with the International Electrotechnical Commission
Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be
used for carrying out the noise monitoring. Immediately prior to and following
each noise measurement the accuracy of the sound level meter shall be checked
using an acoustic calibrator generating a known sound pressure level at a known
frequency. Measurements may be accepted as valid only if the calibration level
from before and after the noise measurement agree to within 1.0 dB.
4.1.6.
Noise measurements shall not be made in fog, rain, wind with a steady
speed exceeding 5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall
be checked with a portable wind speed meter capable of measuring the wind speed
in m/s.
Air Quality Monitoring
Stations
4.2.1.
The air monitoring stations for the Project are listed and shown in Table
4.2 and Figure 4.1. Appendix 4.1 shows the established

The station ID and monitoring location was updated in December 2014 with
respect to monitoring station relocation.
Air Monitoring Parameters,
Frequency and Duration
4.2.2.
One-hour and 24-hour TSP levels should be measured to indicate the
impacts of construction dust on air quality. The 24-hour TSP levels shall be
measured by following the standard high volume sampling method as set out in
the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix
B.
4.2.3.
All relevant data including temperature, pressure, weather conditions,
elapsed-time meter reading for the start and stop of the sampler,
identification and weight of the filter paper, and any other local atmospheric
factors affecting or affected by site conditions, etc., shall be recorded down
in detail.
4.2.4.
For regular impact monitoring, the sampling frequency of at least once
